ELMER F. WALDNER, OF EUREKA, CALIFORNIA, ASSIGNOR TO ANTON HANSON, OF SAN FRANCISCO, CALIFORNIA.

WINDOW-SHADE.

Application filed March 30, 1916.

To all whom it may concern:

Be it known that I, ELMER F. WALDNER, a citizen of the United States, and a resident of Eureka, county of Humboldt, and State of California, haveinvented a new and useful Improvement in Window-Shades, of which the following is a specification.

The invention relates more particularly to vertically adjustable shades in which the roller is movable toward and away from the top of the window, so that any portion of the window may be uncovered or covered by the shade as desired.

Another and more specific object of the invention is to provide in an adjustable shade of this nature means whereby the roller will be rotated as the shade is being adjusted vertically.

Heretofore, when it has been desired to shade the lower portion of the window and leave the upper portion uncovered, the roller has been placed at the bottom of the window 1 and the shade string run around a roller or pulley at the top of the window so that the shade may be raised and lowered.

In this construction the roller was fixed against the vertical movement and thereforeit was impossible to uncover the lower portion of the window without entirely winding the shade. My improved construction is superior to the one here described, inasmuch as the roller is hung to rotate in the customary manner and it may be moved to any position desired in respect of the window.

The invention also aims to generally improve devices of this nature to render them more practicable, durable'and commercially desirable.

With these and other objects in view, the invention consists in such novelty of construction, combination and arrangement of parts as will be hereinafter fully described, illustrated and claimed.

In the drawings:

Figure 1 is a front elevation showing my improved shade in position on a window frame.

Fig. 2 is a side or end elevation showing the shade on the window frame.

Fig. 3 is a fragmentary side elevation showing one of the shade brackets and the wheel which causes the shade to rotate as it is adjusted vertically.

Fig. 4 is a View taken on the plane at Specification of Letters Patent.

right angles to the plane of Fig. 3, showing the roller, the wheel, the brackets, and the wire which serves to rotate the wheel.

Fig. 5 is a side elevation of the spring drum, the casing being partly broken away to show the spring, and

Fig. 6 is a transverse section on the plane of line 66 of Fig. l, showing the con struction of one of the guides and the manner in which the brackets are secured thereto.

Referring in detail to the drawings by numerals, l designates as an entirety a window casing of any construction, having a top horizontal bar 2 and side bars 3, 4:, to which my improved shade is shown secured.

In the preferred embodiment of the invention, a pair of guides 5 and 6 are provided, said guides being rigidly secured to the window casing in spaced parallel re lation. Each of the guides is provided with a base portion 7 carrying an outstanding angular flange 8, as best shown in Fig. 6. The guides are mated so that the angular flanges 8 project outwardly with respect to the vertical center line of the window. These guides may be made of any suitable material and may be secured in position by any desired means.

Slidable upon the flanges 8 of the guides are the shade brackets or runners 9 and 10.

'3, and which is provided with a pivoted locking hook 13 to hold the roller in position as is hereinafter set forth.

On both ends of the bases of the flanges 11 are provided the hooked extensions 14 and 15 which extend across the outer faces of the flanges 8, then rearwardly toward the window frame, and then laterally to hook underthe extensions on the flanges, as is clearly shown in Fig. 6.

The upper extensions or hooks 14: are formed with ears 15' to which are connected the cords 16 which run around the rollers or pulleys 17,. secured in the brackets 18 on the upper end of the guides 5 and 6, and which are connected to opposite sides of the spring drum 19 so that when the drum rotates, the cord will either be wound or unwound. As shown best is Fig. 5, the spring drum is mounted on a pivot 20 to which is connected one end of the spring 21, the other end ofsaid spring being Connected to the interiorof the casin This casing or drum is provided on its periphery with the double channels 22 and 23, one channel being for each of the cords 16.

The spring 21 is always under tension the bracket 10, and the squared end on the other end of the roller being removably fitted into a wheel 28 which is formed on its outer face with a stud or trunnion 29 having a head 30. The trunnion passes through the slot in the flange 11 of the bracket 9 and is removably locked therein by the hook 13 as shown in Fig. 3.

The purpose of the wheel 28 is to turn the roller 27 and wind up or unwind the shade as the roller is moved vertically, and to cause the wheel to turn so that it will properly fulfil its object, a wire 31 is provided. This wire is secured at its upper end to the bracket 18, is looped once around the wheel 28 and is secured at its lower end to the bracket 32. The wheel is grooved in its periphery as shown in Fig. 4 and, therefore, there is no danger of the Wire becoming disengaged therefrom.

In operation the roller may be adjusted to "any position with respect to the windowby of the drawings, the shade maybe pulled down or raised in the ordinary way by means of the string 33, orif desired, the roller 27 may be raised or lowered by means of the spring 24, as previously described. The spring 21 is much stronger than the Copies of this patent may be obtained for spring in the roller so that the shade may be pulled down by the string 33 without causingthe roller to descend.

The wheel 28 and wire 31 which cause the roller 2'? to rotate when it is adjusted are of essential importance to the proper operation of a window shade of this nature, and it is desired to emphasize the fact that when the roller'27 is being raised or lowered this wheel and wire cause the roller to unwind or wind. the shade 26 without substantially altering the position of its lower edge.

While I have shown and described the preferred embodimentof my invention, it will be understood that Ido not wish to be limited to the exact construction and arrangen'ient of parts illustrated and described, but maymake such changes from time to time as may suggest themselves and as fall within the scope and spirit of this invention.

I claim: (j

1. In an adjustable window shade, a shade roller, 'ertieally adjustable brackets supporting said roller, vertical guides to which said brackets are slidably connected,means for ralslng and lowering said brackets, and

engagement with the trunnion end of the' shade roller and with said wheel, a Wire looped around the periphery of the Wheel and secured at its ends and means for raising and lowering the brackets, said Wire serving to rotate the shade roller when the brackets aremoved.

3; An adjustable window shade comprising a shade'roller, a shade carried by said roller, brackets to support the roller, means for raising or lowering the brackets, a Wheel fired at oneend of the roller, and a wire secured at its ,ends andiooped aroundsaid wheel, whereby the roller is rotated when raised or lowered independently of the curtain.

In testimony whereof, I have hereunto se my hand at Eureka, California, this 9th day of March, 1916.
